Translate Article

T.C. Koopmans was born in 1910 at ‘s Graveland, The Netherlands, and died in 1985 at New Haven, USA. His MA was from Utrecht in 1933 in mathematics and theoretical physics, and his Ph.D. was from Leiden in 1936 in mathematical statistics with applications to economics. His career was rather peripatetic for eight years: the Netherlands School of Economics, the League of Nations in Geneva, Princeton University, New York University, the Penn Mutual Life Insurance Company, and the Combined Shipping Adjustment Board in Washington (where he worked on the problem of optimizing the allocation of ships during the Second World War). Then in 1944 he joined the Cowles Commission for Research in Economics at the University of Chicago, where he remained until 1955 when the entire Cowles group moved to Yale. He retired from Yale in 1981. He was Research Director of the Cowles Commission at Chicago from 1948 to 1954, and of the Cowles Foundation at Yale from 1961 to 1967. He was a member of the economics faculty at Chicago from 1946 to 1955, and at Yale from 1955 to 1981.KeywordsActivity analysisAdditivityAmerican Economic AssociationBusiness cyclesCowles CommissionDantzig, G.Econometric SocietyEconometricsEfficient allocationEstimationExhaustible resourcesFelicity functionFisher, R.
